Constituents of the Essential Oils of Helichrysum graveolens (Bieb.) Sweet from Turkey

Abstract

In this study, the essential oils of Helichrysum graveolens species from Turkey were investigated and 72 components were identified by GC, GC-MS. Essential oil was hydrodistilled by using Clevenger apparatus from the aerial parts of plants collected from the natural habitats. The essential oils yield is very low and 0.1 (v/w). Seventy two constituents were comprised the 82.97 % of the total essential oil extracted from the Helichrysum graveolens. The predominant compounds of Helichrysum graveolens were as alpha-cubebene (10.5 %), beta-caryophyllene (9.4 %), azulene-octahydro (7.5 %), caryophyllene oxide (8.2 %). The results were discussed in view of chemotaxonomy and natural products.
